There's not enough shovels to make Bixby pay for being such an arrogant jerk. Just because he has his tail between his legs doesn't mean he's a changed man.

The same goes for the Gatekeeper. He had power, he was happy, people were not killed. I don't feel assured with the possibility of him being forever The Great Leader of The Colony, it must have taken some time for Marcus to be a crappy leader and an abusive force. Until this point I've seen nothing but Gatekeeper acting like a psycho nutfreak. My bet is that if the Mallers never went to the Colony, he would eventually be as abusive as Marcus. So, yeah, I would never miss Gatekeeper if CJ went Katana Power Chopchop on him.
